BIOLOGICAL VALUE OF PROTEIN
Let's discuss in detail about how our muscles tissues or muscles protein is being formed by food protein , the protein sources we eats regularly. As UNIVERSAL fact about body is that it can not store protein or amino acid we eat as like fats and carbohydrate which are stored for latter use. The human body rejects or excrete the extra protein (or amino acids)which we are eating. Thus we need exact daily amount of protein per day to meet up bodily protein requirement and save our tissues from breakdown.
Coming to our topic the wellness and absorption of any protein is can be traced by it's biological value. The BIOLOGICAL VALUE (BV) pf protein is a scale from 0 to 100, which describes how well the body tissues can be created from food protein which we are eating.
The Biological Value (BV) is a scale of measurement used to determine what percentage of a given nutrient source is utilized by the body. The scale is most frequently applied to protein sources. Biological Value is derived from providing a measure intake of protein, then determining the nitrogen uptake versus nitrogen excretion. The theoretical highest BV of any food source is 100%. In short - BV refers to how well and how quickly your body can actually use the protein you consume.
The BV of food depends upon how closely it's amino acid pattern reflects the amino acid pattern in the body tissues.The better the match , the more completely food proteins turn into body proteins . When a protein contains the essential amino acids in a proportion similar to that required by the body, it has a high Biological Value. When one or more of the essential amino acids are missing or present in low numbers, the protein is has a low biological value.
The animal drives protein sources has similar amino acid pattern as human thus this match more to our muscles tissues. thus the animal protein sources has greater biological value as compared to plant proteins. The BV is very important for vegetarians and vegans, who do not consume animal protein. In general, animal proteins have a higher BV than vegetable protein, due to the resemblance of humans and animals. Vegetarians and vegans thus should cleverly select protein sources to obtain a high BV.

BONUS TIP:-
High protein diets automatically reduce the biological value of all proteins consumed, because the body is getting more amino acids than it can actually metabolise at any given time.
